What It Could Mean?
Although the studies on both conditions are relatively small, the results suggested there may be a stronger relationship between ADHD and hoarding than between OCD and hoarding.
However, because ADHD and OCD are considered comorbid, or coexisting, conditions, there may be some overlap between all three conditions.
You might be wondering if other comorbid conditions to ADHD are related to hoarding, such as stuttering or dyslexia. There is little research on the link between these. Although it is common for dyslexia [3] to accompany ADHD, more research is needed in this area to determine if hoarding is also connected to the speech condition.
